SUBJECT: Compliance Evaluation Inspection and Notice of Violation
NOV Tracking Number: NOV-2018-PC-0234
Hebron Colony and Grace Home WWTP
NPDES Permit No. NC0032191
Watauga County
Dear Mr. Holder:
On June 27, 2018, Kelli Park and Gary Hudson, of this office, met with Brandon
Hughes, ORC, to perform a Compliance Evaluation Inspection on the Hebron Colony and
Grace Home wastewater treatment system. This type of inspection consists of two basic
parts: an in-office file review and an on-site inspection of the treatment facility. The
attached EPA inspection form notes the areas that were evaluated for this inspection.
The findings and observations are outlined below:
I. Permit
The NPDES permit became effective December 1, 2017, and expires September 30,
2022. The facility had an expired copy of the permit available during the inspection.
Please update the permit on site.

II. Self-Monitoring Program
A review of the monthly discharge monitoring reports (DMRs)for the period January 2017
through November 2017 showed that the facility was in compliance with all permit limits.
III. Flow Measurement
The flow meter was calibrated in July of 2017. It needs to be calibrated before August 1,
2018. Please send a copy of the calibration certification to Ms. Park upon completion.
IV. Operations and Maintenance
The wastewater treatment plant appeared to be very well maintained and operated
V. Facility Site Review
Most of the components of the 0.0093 million gallons per day facility appeared to be
functioning properly. The aeration basin had a light brown color and a good earthy odor.
Although the dissolved oxygen (DO) wasn't measured during the inspection, Mr. Hughes
indicated the aeration basin (AB) normally runs at about 0.8 milligrams per liter (mg/I).
Please note a more preferable range for DO in the AB is 1.0-3.0 mg/I. One ultra violet
(UV) bulb was down, but Mr. Hughes had taken a fecal sample and said that they are still
in compliance. That bulb needs to be replaced as soon as possible. Please send Ms. Park
a verification email once it is replaced. There were no extra bulbs or chlorine on site as
backup for disinfection. These should be available in case of technical malfunctions.
VI. Records/Reports
The visitation log is on site and show visitation times and plant conditions. Chain of
custody forms and calibration records are in good order. All of the required monitoring
was performed per the,frequencies specified in the NPDES permit. When checking the
DMRs and bench sheets, Ms. Park found that two TSS results were not properly
transcribed to the DMRs. On March 21, 2018 and March 28, 2018 the reported value was
7 mg/I while the bench sheet showed 14 mg/I.While these numbers are still in compliance,
diligence should be used when reporting analyzed values.
VII. Effluent/Receiving Waters
The effluent from the facility was clear the day of the inspection. Effluent was being
discharged into the Watauga River, class B; trout; high quality waters in the Watauga river
basin.
Please work to correct the deficiencies in paragraphs 5 and 6. .
